This is undoubtedly an optical illusion, but it’s so cool to have even a slight hope for something like this…

A photo of two peculiar dragon-shaped objects taken from a plane flying over Tibet’s Himalayas piqued many users’ interest when displayed on a Chinese website. The photographer is an amateur.
On June 22, 2004, the photographer went to Tibet’s Amdo region to attend the Qinghai-to-Xizang Railroad laying ceremony, and then took a plane from Lhasa to fly back inland. When flying over the Himalayas, he accidentally caught these two “dragons” in a picture that he took. He called these two objects “the Tibet dragons.”
Looking at the photo, these two objects appear to have the characteristics of crawling creatures: The bodies seem to be covered by scales, the backs have spine-like protuberances, and also they have gradually thinning rear ends. Although the photo caught only a portion of the entire scene, it was sufficient to create the appearance of two gigantic dragons flying in the clouds.
